Start by making the sauce. Place mayo, adobo sauce, lime juice and cilantro in a small bowl. Now this is the hard part. Stir it all together. Cover it and set in the fridge.

Now place the beef in a bowl and gently crumble with your fingers. Add the chipotle peppers, adobo sauce, grated onion, garlic powder, cumin, kosher salt, and pepper. Use your hands (yes, your hands!) to gently mix things together. If you go crazy and over-work ground beef it gets a yucky texture. Just mix it enough to distribute the ingredients and call it good. Divide into 4 patties (or 6 little ones) and place on a preheated grill, indoor grill pan, or skillet. When the burgers are done to your liking let them stand for 5 minutes off the grill/pan and then pop onto your prepared buns. Top with chipotle-lime mayo, tomato slices, avocado slices, and a crisp piece of lettuce.
